What grain of bullet do you use in your 20 caliber rifle ?
When the OP asked his original question's he stated that he also wanted to do some long range shooting. My interpretation of long range starts at 500 and continues past that. Past that the 204's start eating dust. My suggestion was fast twist first, then caliber. 223 with heavier bullets will get
him into long range stuff economically. Shoot 55's or less for flatter trajectories close in- this is where the 204 shines.
He could go with a fast twist in 22-250 too to "get all he desires" but i think the 223's would be a better starting point.
As with all calibers there are compromises including the 204 and 223.
From what i have been reading you are obviously very knowledgable in the ballistics field- much more than i and a more accomplished shooter.
This post is not intended to smear the 204's or the fans of them. I am one.

You are right about factory 204 Rugers shooting the 40 grain bullets like crap because they have 1-12 twist and too much freebore. My brothers Rem 700 VSSF II shot 4.5" with the Hornady factory 40 V-Max. I did manage to get 2.5" but had a hard time getting it to shoot 32 V-max hand loads better than 3/4" as well. My CZ527 V, with 25 5/8" barrel shoots the factory 40's into 1MOA at near 3900 fps on a cool day so go figure. You are right in that we are talking 500 yard varmint gun at best.
Going to the heavier bullets with faster twists will extend the range in all three mentioned calibers. You will probably only find the faster twist in a 223, unless you go custom, but then you will probably find that you have to feed it single shot to get satisfactory results. The Berger 55 VLD would likely surprise you in a 20 Tactical or 204 Ruger with a 1-7 twist unless you try to load it to fit the magazine.
This is why I designed the 20 EXTREME. I can run 204 Ruger/20 tactical velocities with 20.6 grains of powder in a 24", 12 twist, barrel. I can run 40 grain bullets to 3650fps which outdoes the Hornady Factory 40 grain 22-250 bullets, to 500 yards, with less than half the powder and recoil.
The 55 Berger fits in the magazine with the bullet seated to the lands and has only about 2 grains less powder capacity than the larger 20 calibers loaded to magazine length. I suspect that I would get close to 3200fps in a 24" barrel.
If I were going to go past 500 yards I would use the old Rem 700 V, 7mm08, with the Speer 110 load that I posted earlier.
